Abstract:
The invention relates to a composite (1) comprising a first semiconductor substrate (4) having at least one MEMS-component (2) and at least one second semiconductor substrate (4), wherein at least one layer (6) comprising germanium is bonded eutectically with at least one layer (3) comprising aluminum. According to the invention, the layer (3) comprising aluminum is provided on the first semiconductor substrate (1) and the layer (6) comprising germanium on the second semiconductor substrate (4). The invention further relates to a production method for a composite (1).
Abstract:
Patterned layers including height control features are stacked and bonded to form microchannels in a micro-fluidic device. The heights of the microchannels are determined by the height control features of the patterned layers. Side walls of the microchannels are partially formed or completely formed by the height control features. Layers are bonded together with a bonding agent disposed between the layers and outside the microchannels near the microchannel side walls. This approach provides numerous significant advantages. Material consumption can be reduced by up to 50%. Mass production can be made easier. Lateral dimensions of microchannels can be more readily controlled. Erosion of the bonding agent by flow through the microchannels can be greatly reduced.

Abstract:
The present invention offers a rapid, low cost, and low temperature process for bonding microfluidic devices, which are composed of at least one plastic substrate, and which is based on the surface modification of the substrates composing the device resulting in the irreversible bonding between the substrates. It is a generic method of bonding of bare or structured substrates at least one of which is a plexiglass (known also as poly(methylmethacrylate), PMMA), or a PS, or an epoxy (such as the commercial photoresist SU(8)) polymeric substrate.
Abstract:
A unitary structure (10) is comprised of two or more planar substrates (30, 40) fused together by a glass or glass-ceramic sintered patterned frit material (20) disposed therebetween. The pattern of the sintered patterned frit material defines passages (70) therein, and the sintered patterned frit material (20) has a characteristic minimum feature size (60) in a direction parallel to the substrates. Particles of the frit material have a poly-dispersed size distribution up to a maximum frit particle size, in a maximum length dimension, and the minimum feature size (60) of the sintered patterned frit material is greater than 2 times the maximum frit particle size, desirably about 3 times or more, and less than 6.25 times the maximum frit particle size, desirably about 5 times or less, most desirably about 4 times or less. A method for making the structure (10) is also disclosed.
Abstract:
L'invention concerne un procédé de protection de l'intérieur d'au moins une cavité (4) présentant une partie d'intérêt (5) et débouchant sur une face d'un élément microstructuré (1), consistant à déposer sur ladite face une couche non conforme (6) d'un matériau de protection, ladite couche non-conforme bouchant la cavité sans recouvrir la partie d'intérêt. L'invention concerne également un procédé de fabrication d'un dispositif comportant un tel élément microstructuré.
